Brief analysis: "Too much Qian Fan is nothing" is a major emotional turning point in the whole poem. This sentence contrasts with the first cheerful mood, bright and strong; It is also connected with the emptiness and anxiety of "leaning alone on the Wangjianglou", connecting the preceding with the following. The boat is empty, how can people be inferior! Hopes were dashed. At this time, what caught her eye was "the water is slanting." Sunset and running water, originally lifeless and heartless things, have become affectionate beings in the eyes of women who think here and now. This is an associative analogy caused by her painful mentality of empathy with natural objects. The sun is about to set, and I am deeply affectionate to the disappointed woman, unable to bear to leave, quietly receiving the afterglow; The endless river seems to understand her mood, and she flows away silently.
